CARL G. G. BERGSTROM, OF ST. PAUL, MINNESOTA.

BAG-HOLDER.

Application filed August 31, 1916.

Edit whom it may concern:

Be it known that I, CARL G. G. BERG- 'STROM, a citizen of the UnitedStates, residing at St. Paul, in the county of Ramsey and State ofMinnesota, have invented a new and useful Improvement in Bag-Holders, ofwhich the following is a specification.

This invention relates to certain new and useful improvements in holdersfor sacks and is particularly designed to engage and retain themouth ofthe sack or bag in distended or in open position, so that it may befimost conveniently filled and packed with grain, articles or produce ofwhatever nature; and as such includes features of improvement over theconstruction illustrated and described in-my Patent Number 1,280,- 060,granted to me on the 12th day of June, 1917, for bag holders.

One of the improved features of the present invention is the provisionof novel means whereby the bag holding elements may be initiallypositioned or adjusted to approximately the size of the mouth of thesack or bag to be filled. Another object is to provide means forengaging the mouth of the bag so that the same may be quickly attachedabout the bag-holding elements and in such manner that the tension aboutthe bag mouth is evenly distributed so as to most effectively extend itfor filling and to minimize the likelihood of ripping or tear ing of thebag.

A further object is to provide a novel means of mounting the bagengaging devices so as to avoid the possibility of personal injury tothe operator or damage to the goods being put into the bag.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claim.

In the drawings, Figure l is a side elevation of the invention showing abag in filling position held thereby; Fig. 2 is a partial section takenon the line XX of Flg. 1 looking'in the direction of thearrow, show ingthe bag holding elements 1n sllghtly' furtherextended position than asillustrated in I Fig. 1; Fig. 3 is an enlarged section taken on the lineYY of Fig. 2, showing the housing and bearing, the latter in dottedlines, for one of the bag engaging members, and Fig. 4: is adetail,'partly in section and broken away, of a'portion of the carriageSpecification of Letters Patent.

mechanism supporting the movable bag holding element.

Like numerals of reference refer to like parts in the several figures ofthe drawings.

In the drawing illustrating this invention, the reference character Arepresents a base or platform upon which is mounted a standard Bcomprising a support 10 rigidly secured in any desired manner to thebase, and a tubular or other shaped member 11 telescoping andlongitudinally movable upon the said support. These parts are fully setforth in my copending application, Serial Number 93,071, filed April 24,1916; but for the purposes of this application, certain of the specificfeatures of construction of said parts'will be here described.

The tubular member 11 is formed of two sections 12 and 13, the upperextremity of the section 12 being enlarged as shown at 14 to receive forsecurance in any preferred method, the lower extremity of the section13. Pivotally secured between a pair of outstanding lugs 15 (only one ofwhich is shown) is a dog 16 held in engagement with longitudinal wavedserrations 17 formed on the support 10 as fully described in mycopending application above referred to. By this means the member 11 maybe moved vertically upon the'support 10 and retained in selectiveposition as and when desired.

Attached about the section 13 of the mem ber 11 is a collar 18 fromwhich extend one or more arms 19 supporting at their outer free ends abag holding element 20 made of any suitable material and configuration,though here shown of segmental contour. At each of its opposite ends,the element 20 terminates in an outstanding portion 21 having anaperture through which a tubular member 22 is adapted to slide for apurpose which will later appear. Telescoping with in each of the members22 is an elongated rod 23, to the outer free ends of which rods aresecured the outstanding portions 24 of a second bag holding element 25here shown as similar in construction and shape as the element 20 abovedescribed. It is to be un derstood that the segmental contours of theelements 20 and 25 extend in opposite directions. At their correspondingends, the members 22 are each provided with a threaded opening, throughwhich a setscrew 26 operates to bind, upon and hold the rods 23 indifferent extended positions.

--by1means-'ofa' threaded bolt 28, (seeFig.

3), a toothed wheel 29 adapted to revolve in a substantially horizontalplane and to ..retain in position thereon a'portion of the to engageandhold the bag, it is equally month of the bag or sack to be filled.IVhile it is necessary that the teeth of 'the'wheels 29 projecta'sutficient distancebeyond the outer convex faces ofthe'elements'20 andnecessary that the portion of the wheels V which extends inwardly,be-protected from clogging vby small grain, -or other articlesdeposited-in the bag, andto eliminate possibility ofpersonal injury-tothe operator or damage to the goods being-put into the bag.

-For' this purpose, the enlargements 27 are provided, it beingunderstood that at their base, the enlargements are of sufficient sizeto entirely cover the inwardly extending portions of the wheels. Byforming-theen- -largem'ents of inverted semi-cone shape,

thereis no possibility of the retention-there on of any of the producebeing put into the bag.

7 At their: free ends each; of the tubular members 22 is pivotallyattached to the end of the long arm'30 of-a bell crank, the angleportion ofwhich is journaled between two lugs 31 (only one being shown)extending outwardly from a yoke 32 having integral projections 33suitably engaging the support '10 for reciprocable movement thereon. Theyoke 32 also has a projection 34 to which one end of a spring 35 issecured, the other end of the spring being attached to the endof theshort arm 36 of the bell crank. By the construction just described, thetension of the spring 35 will cause the element 25 to move forcibly awayfrom the stationary ele ment 20. As more fully set forth in my copendingapplication, the apparatus includes evener'rods 37 (only one being hereshown) pivoted at one end to the collar-18 carried by the tubularsection 13 and the other end to the long arm 30 of the bell crank, theobject of such evenerrods being to effect aneven up or down movement totheyoke 32 when the movablebagelement and its supporting or carriagemechanismis moved in toward or away from the stationary-bag element and'to thus eliminate'any binding tendency of the parts in their severalmovements.

done, and the set screws 'retightened, the

bag element 25 is forced inwardly against the tension of the spring 35asuflicient' distance to enable the bag mouth'to be'secured" about-theseveral wheels 29 'onb'oththe'elements when the force a'gainst'theelement 25 is removed and such element thrown outw'vardly by the actionof spring'35 so'as to {the bag'mouth is evenlydistributed, so that thereis no'saggingof the bag orany' likelihood of its being ripped or torn.In accordance with the patent statutes, I have described theprinciplesof ope'ration of-my invention, together with the apparatus which I nowconsidertorepres'ent the best embodimentthereof, but I desire to T haveit understood that the construction shown is only illustrative, and thatthe invention can be carried out by other means and applied to usesother than those'above set forth within the scope of the following 1claim. 7

Having described my. invention, what I claim as new and desire to'protect by Letters Patent is: j

A bag holder, comprising, in combination, a standard, a plurality of,bagholding elements supported by said standard, oneof said elementsbeing movable awayrfrom the other, and both of said elements being fiatupstanding bands of segmental contour extending in opposite directions,and a series ofclosely placed freely rotatable bag engag ing elementsjournaled onthe lower-edge of each and projecting inwardly and outwardlyfrom the concave and c'o'nvex'sides of said bands to tensi'onallyengage-and retain in curved open position the mouth 'of a bag and toevenly distribute the-tension. about the bag mouthysaid bands beingformed with-guides over the instanding portion of each rotatable bagengaging, element.

In testimony- "whereof, I have; signed my name-to this specification.
